I know that a lot of people on here have said that once you get the clutching dialed in, the XP's will do anything. Do you still have to mess with the clutching on the 09's because I just got the blue summit X home the other day and just the little bit i have moved it, the clutch doesn't kick in till right about 5000 RPM. Is that normal?

your elevation might have a effect on it--i'll ck ours in the morning but they seem around 3500 or so

the wifes new one is around 5000 too.its 5000 ft here.but i have no clue about a doo.thought it was normal.LOL
Wait till your riding down the trail going 15mph and the motor is spinning 7000RPM's just heating the belt up. This was on my 08, but by far the biggest junk setup I have ever seen. I have part out on my bench to replace the ramps, pins, spring, secondary spring and helix. Other than that Ski-Doos setup rocks!!!

well that makes me feel better.LOL.what do the adjustment bolts on the primary do?

THey change to angle of the ramp. Higher the number, slower shift, more R's, lower number faster shift, less R's.
XP is an awsome sled...I rode mods for years and was anxious about going to a stocker but it does not disapoint. Just the clutching from the factory is way off....on the 08's

Mine is about the same It engages at about 3800. And im at 1800 ft
We are all hoping the clutching is better than the 08 XP. Especially since doo seems to have spent a lot of time developing the 09' clutching and as a result has pretty much replaced every part that affects how the clutches perform.
I wouldnt worry about the clutch engagement until you get some good break in miles on it. Things should loosen up.

who is your dealer and did you pay to have it setup properly?
If they uncrated it and said here you go, I would bet you could see just about anything and everything regarding setup..... it pays to use a dealer that actually tests there clutching setups so you get something ridable from day one
My dealer had prototypes of these new clutch parts last spring so his setup should be close, but he told me once the snow hits and they are able to fine tune for production parts, he will call me if there are changes
I saw this one coming. As soon as I heard that it was a green/purple spring I knew there would be complaints. Thats 200/320. Last year the sleds came with purple/purple, which is 160/320. Most guys I know went to blue/(blue or purple) 130/(290 or320) to lower the engagement from (4200-4400) to (3800-4000). This was better to reduce trenching off the line.
There are other ways to lower angagement....perhaps the new ramp profile needs more spring?
I hope so but I did change my ramps on my 08 and from what I can tell they would have to be very tall on the pin end to make a difference. This being said has anybody opened their clutch yet to take a look? This would be a good idea just to clean any sticky oil if present. I would be very interested in seeing the new ramp. Anybody got the ambition to remove a ramp and trace out and post a scan of it here?
You gotta be kidding
No-one even has 1 mile on an 09 yet. You have your sled sitting in your garage and are running it up to where the clutch engages and you are already trying to mod it. The only parts on the primary and secondary that are the same are the sheeves so trying to compare it to an 08 doesn't work. Go for it. Start throwing darts at it or throw it up againgst the wall and see what sticks. I think I'll make sure my clutch and belts are clean and get through the first 10 hr check and let the motor loosen up a bit before I start messing with the clutch.

I don't know the 441 ramp profile but looks like they went backwards to me. 200/320?? Yikes...I have the 130/290 in my 08 right now and it still sucks on the bottom. No bite at all just Revs and goes no where. The ramps that came in the 08's are junk and mine are going in the garbage. Putting something in the shift harder all the way through. maybe go back to the 160/320 to get engagement back up a little. I like sled that when you breath on the throttle they jump out from under you...that lazy slow track speed for non trenching is BS. How many people you see when they are stuck take off slow??? 95% of people grab a fist full of throttle and go for it.....why would you want to make it lazy with a non agressive setup....never did understand that logic....

our 09 x's are about 4200 rpm,s
relax , relax relax .. wait till you have it in the snow and have 3 tanks thru it before you go and throw a pill of cash around .
contrary to most thoughts on last years clutching on the 08 ..doo only missed with one componnent in the transmission .
one underlaying issue the 08 had was a very short life on the spring tower capbushing clearance. 07/08 the materials wer soft and achieved a to broad a clearence very shortly and would effect transmission oporation emmensely .
if the tower cap is good the item i talk about is the end load on the secondery spring .it was to soft for the type of track doo selected . duro was hard and lugs didnt bend much , this translates to a much higher load and a strain in the secondery as it up shifts and looses the amount of belt traction patch.
we tested all season on the doo transmission and we as well put the team secondery on to verify that we werer on the correct track , we saw the exact same symptoms and it took the exact same direction to correct it ,
when we did we saw the track speeds increase to were we thought the new chasi would send it .
no gearing change needed .
163 track speeds went from a typical deep snow scenario here of 37 mph to 54.
the 154 saw the same jump in track speed and the belts were at a temp and wear factor that was now acceptable .
the 09 approach does make me scratch my head but i want to seee what it actually does first before the speculatiion goes wild .
for 09 ski doo has changed the spring tower cap material and assure me they have it fixed . we hope so and will be the component that we watch closely out of the gate .
remmember relax relax relax till the sled proves to us we need to change it .
doo spends a lot of effort in trying to deliver a middle of the road set up that as it goes out the dealer s responsability for the fine tunning his customers need for there riding area is left on there shoulders .
all things said we put a yellow epi sec spring in last years sec , it was a 50 lb increase over what doo sent out and this one item made the sled absouloutly rock . no other changes needed .
on a note we achieved the highest track speed in deep snow going vertical on the gps with this set up in our big bore on this motor .
over all you should achieve a 7 mile an hour gain over the older rev chassi if you get the clutching correct and as well if it doesnt have a worn spring tower cap .
this bushing carries an immence load and when it wears pre maturely it is no wonder a lot of chasing was done 07/08 to find a good set up .

Good right up turboal. I have a stiffer secondary for mine also out on the bench. Stock the primary works pretty good at WOT but on the trail and bottom the lazy shift drives me nuts. The turning 7 grand down the trial is obnoxious also. Did you gear the 154's down to 19 or keep the 21 in??
no , actually we kept the gearing once we got the end loadcorrect . you could gear down , just need a bit more tip weight to get the up shift back .
we used the 2mm over size rollers to achieve this '.
we combined this with the shaving of the power valves 200ths . this puts the export opening when the guilletines are closed back close to were it was on the 06 model 800.
they use the opening of the power valves at 7400 as a wa to beat the sound emmissions test on the tail . you can pass by at 45 mph and not be intothe power valves as when they open they exceede 100 decibels .
the larger opening allows the pipe to come to pressure sooner and gives you the mid range pull you are used to on the older 800 motor it oopened at 5800rpm and in its closed position it was a 30 mm opening and the r motor is 25mm.
